What do flat rooflights involve?
Our flat rooflights service in the Forth Valley covers fixed double or triple glazed rooflights for flat roofs and extensions. We survey every job before fixing the price.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. Scottish weather is hard on roofs, so we specify rooflights and roof windows with exposure in mind and fit upstands with generous heights.

Planning and building rules in Scotland
Scottish householder permitted development (Class 2B, other external alterations) can cover a rooflight that projects no more than 1 metre from the roof, but the right does not apply in conservation areas. Listed buildings need listed building consent where the work affects their character.
Scottish energy standards for glazing, including rooflights, use an area-weighted average of 1.4–1.6 W/m²K in extensions, so most modern units comply comfortably. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Will it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
Can a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
Do I need to be at home for the survey in the Forth Valley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
